  • 摘要: 探究了高效合成杂环酮衍生物的方法:用3-取代BINOL酰胺( )催化杂环酮与醛的羟醛缩合反应中,高收率、高对映选择性地合成了杂环酮衍生物,并考察其催化活性. 研究结果表明:Ⅰ(x=15%)为催化剂,CH2Cl2为溶剂,于0 ℃反应24 h,杂环酮与醛能有效进行羟醛缩合反应,获得较好的收率(最高89%)和较高的对映选择性(最高91% ee)

     

    Abstract: The highly efficient method of synthesizing heterocyclic ketone derivatives was explored. In the aldol condensation reaction of heterocyclic ketone with aldehyde catalyzed by 3-substituted BINOL amide (Ⅰ~Ⅴ), the heterocyclic ketone derivatives were synthesized with high yield and high enantioselectivities, and their catalytic activity was investigated. The results demonstrated that in the presence of shaft chiral catalyst (x=15 %), the aldol condensation reaction between heterocyclic ketone and aldehyde can be effectively carried out, under the conditions of 0 ℃ in CH2Cl2. Both higher yield (up to 89%) and better enantioselectivities (up to 91%ee) could be obtained.
